* chunk: Add function to calculate Internet Checksums according to RFC 1071Tobias Brunner2014-07-221-0/+31
|
* unit-tests: Seed chunk_hash() only once, but before creating any hashtablesMartin Willi2014-06-041-0/+8
| | | | | | | Due to the removal of pthread_once, we manually create the seed for chunk_hash(). With the new testable functions interface, this won't work for the hashtable initiated using __attribute__((constructor)). Enforce seeding before creating that hashtable.
* chunk: On Windows, use binary mode in chunk_write()Martin Willi2014-06-041-1/+8

* chunk: On Windows, chunk_map() opens files in binary modeMartin Willi2014-06-041-2/+7
|
* chunk: Fallback to recv() on Windows chunk_from_fd() when operating on socketMartin Willi2014-06-041-0/+6

* chunk: Don't depend on pthread directlyMartin Willi2014-06-041-13/+5
|
* chunk: Externalize error reporting in chunk_write()Martin Willi2014-01-231-9/+6
| | | | | This avoids passing that arbitrary label just for error messages, and gives greater flexibility in handling errors.
* chunk: Provide a fallback chunk_map() if mmap is not availableMartin Willi2014-01-231-1/+46
|
* chunk: Use dynamically allocated buffer in chunk_from_fd()Martin Willi2014-01-231-12/+41
| | | | | | | | When acting on files, we can use fstat() to estimate the buffer size. On non-file FDs, we dynamically increase an allocated buffer. Additionally we slightly change the function signature to properly handle zero-length files and add appropriate unit tests.
* chunk: Add functions to map file contents to a chunkMartin Willi2014-01-231-0/+80

* chunk: Add helper function to create a chunk from data read from a file ↵Tobias Brunner2013-10-231-0/+32

* chunk: Print chunks without separator if + modifier is usedTobias Brunner2013-08-241-2/+2
|
* chunk: Add predictable hash functionTobias Brunner2013-06-281-0/+22
| | | | | Since chunk_hash() is randomized its output is not predictable, that is, it is only within the same process.
* Randomly allocate chunk_hash() key during first useTobias Brunner2013-06-111-1/+46
| | | | This avoids hash flooding attacks.
* Replace chunk_hash() with output from chunk_mac()Tobias Brunner2013-06-111-75/+23
| | | | | | | The quality is way better, the calculation is a bit slower though. The key is statically initialized to zero, which will be changed later to prevent hash flooding.
* Adding chunk_mac() which calculates a 64-bit MAC using SipHash-2-4Tobias Brunner2013-06-111-1/+117

* Moved chunk_t to utils folderTobias Brunner2012-10-241-0/+690
